Hello Howard, Yes maybe your idea has some merit. Why I am answering your post, is the sharks that always seem to get me when I jump in boots and all. Firstly the old trick with the postage it is nearly always overlooked. One occasion springs to mind a chap I had met a couple of times at Ballarat Swap from down the Murray River, rings and asks for some early veteran 2 speed cases with the large hole in one end and the extension the other. Yes I had 3 mismatched numbered halves for $20. I posted on and the package clearly marked with the postage costs ( $13.50), and yes within days a postal note arrived for $20. I lost some valuable parts for $6.50, bargain? Yes I know I probably have some valuable wanted parts stashed away, but the old trip to the PO, cant really be bothered. Prefer personal shoppers or swap meets. regards Al
